android 解决datepicker和timepicker一起用引起的布局样式问题

最近需要用到datepicke和timepicker一起用，但是发现个问题，通过XML布局文件无法跳转大小样式，XML文件内容如下

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <DatePicker
        android:id="@+id/date_picker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:calendarViewShown="false" />

    <TimePicker
        android:id="@+id/time_picker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical" />

</LinearLayout>

屏幕大的手机能显示全，但是小的就这样了，最后经过查阅资料解决了这个问题，解决方案如下：

/**
	 * 调整FrameLayout大小
	 * @param tp
	 */
	private void resizePikcer(FrameLayout tp){
		List<NumberPicker> npList = findNumberPicker(tp);
		for(NumberPicker np:npList){
			resizeNumberPicker(np);
		}
	}
	
	/**
	 * 得到viewGroup里面的numberpicker组件
	 * @param viewGroup
	 * @return
	 */
	private List<NumberPicker> findNumberPicker(ViewGroup viewGroup){
		List<NumberPicker> npList = new ArrayList<NumberPicker>();
		View child = null;
		if(null != viewGroup){
			for(int i = 0; i < viewGroup.getChildCount(); i++){
				child = viewGroup.getChildAt(i);
				if(child instanceof NumberPicker){
					npList.add((NumberPicker)child);
				}
				else if(child instanceof LinearLayout){
					List<NumberPicker> result = findNumberPicker((ViewGroup)child);
					if(result.size()>0){
						return result;
					}
				}
			}
		}
		return npList;
	}
	
	/*
	 * 调整numberpicker大小
	 */
	private void resizeNumberPicker(NumberPicker np){
		LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(80, LayoutParams.WRAP_CONTENT);
		params.setMargins(10, 0, 10, 0);
		np.setLayoutParams(params);                                                                            
	}

然后这样调用就行了：

 final DatePicker datePicker = (DatePicker) view.findViewById(R.id.date_picker);  
        final TimePicker timePicker = (TimePicker) view.findViewById(R.id.time_picker);
        resizePikcer(datePicker);//调整datepicker大小
		resizePikcer(timePicker);//调整timepicker大小

看下调整后的效果图吧：

是不是很简单呢，文字也可以改变，通过style,例子下载地址如下：
